A faulty MAP sensor can cause some fuel delivery problems and not turn on the SES light. Some other symptoms are bad gas mileage, engine hesitation, sparkplug misfire, or trigger the SES light. The best bet if you suggest the MAP sensor is bad is to check the engine codes.

These symtoms may occur when the map sensor is bad: Surging, rich fuel which could foul the spark plugs, loss of power, poor fuel economy, and Detonation due to too much spark advance and a lean fuel ratio.
